"The pearl earring, why would the murderer take it? Was it accidentally ripped off?"
"I think so. The courtyard was shared by two people, and over several months, there should be traces left. But when we checked, all traces of the other person were wiped clean. That's not something an ordinary person could do."
"But that's also strange, Liu Chu erasing traces to create the illusion that he was never there and accidentally ripping off the pearl earring, then having to take the other one too. But using a blunt weapon to kill someone is conspicuously evident. If Liu Chu was the one erasing the traces, isn't that like the old saying 'there is no silver here just by stating it'?"
